Non-line-of-sight radar-based gesture recognition
First Claim
1. A computer-implemented method comprising:
- receiving or capturing an image of a room from a perspective of a non-line-of-sight gesture-recognition system;
receiving or determining dimensions of the room; and
determining, based at least in part on the image and the dimensions of the room, a volume of the room in which there is no line-of-sight to the non-line-of-sight gesture-recognition system; and
determining, by providing radar transmissions from the non-line-of-sight gesture-recognition system and into the room, a set of transmission paths sufficient to cause a reflected radar field to be provided within at least a portion of the volume, the reflected radar field enabling capture of gesture interactions with the reflected radar field.

Abstract
This document describes techniques and devices for non-line-of-sight radar-based gesture recognition. Through use of the techniques and devices described herein, users may control their devices through in-the-air gestures, even when those gestures are not within line-of-sight of their device'"'"'s sensors. Thus, the techniques enable users to control their devices in many situations in which control is desired but conventional techniques do permit effective control, such as to turn the temperature down in a room when the user is obscured from a thermostat'"'"'s gesture sensor, turn up the volume on a media player when the user is in a different room than the media player, or pause a television program when the user'"'"'s gesture is obscured by a chair, couch, or other obstruction.

7. A computer-implemented method comprising:
-
providing, through a non-line-of-sight gesture-recognition system, a radar field within a room, the radar field including direct radar fields and reflected radar fields, the reflected radar fields being reflected off of a surface of the room and provided in one or more volumes in the room to which direct line-of-sight from the non-line-of-sight gesture-recognition system is not available; receiving a reflection of a gesture interaction made within the radar field within the room, the reflection enabling capture of data about the gesture interaction; determining a gesture based on captured data associated with the reflection of the gesture interaction; and providing the gesture to a device or application effective to control the device or application. - View Dependent Claims (8, 9, 10)

11. A computer-implemented method comprising:
-
providing a radar field; sensing reflections from an interaction that is within the radar field; recognizing, at a smart device associated with the radar field and based on the reflections from the interaction that is within the radar field, a gesture; determining that the gesture is associated with a non-line-of-sight smart device; and passing the gesture from the smart device to the non-line-of-sight smart device in a format usable by the non-line-of-site smart device to recognize the gesture and effective to enable the gesture to control the non-line-of-sight smart device or establish communication with the non-line-of-sight smart device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
